TEMPERATURE VALUE REGISTER
The temperature value register stores the temperature measured
by the internal temperature sensor. The temperature is stored as
a 16-bit twos complement format. The temperature is read back
from the temperature value register (Register Address 0x02) as a
16-bit value.
Bit 2, Bit 1, and Bit 0 are event alarm flags for T
T
to a 16-bit digital value, Bit 2, Bit 1, and Bit 0 are no longer used
as flag bits and are, instead, used as the LSB bits for the extended
digital value.

Temperature value in twos complement format.
Sign bit, indicates if the temperature value is negative or positive.
Description
Flags a T

Contains the Least Significant Bit 0 of the 15-bit temperature value if the
configuration register, Register Address 0x01[7] = 1 (16-bit resolution).
Flags a T
(13-bit resolution). When the temperature value is above T
Contains the Least Significant Bit 1 of the 15-bit temperature value if the
configuration register, Register Address 0x01[7] = 1 (16-bit resolution).
Flags a T
(13-bit resolution). When the temperature value exceeds T
Contains the Least Significant Bit 2 of the 15-bit temperature value if the
configuration register, Register Address 0x01[7] = 1 (16-bit resolution).

ID REGISTER
This 8-bit read-only register stores the manufacturer ID in Bit 7
to Bit 3 and the silicon revision in Bit 2 to Bit 0.
T
The 16-bit T
stores the critical overtemperature limit value. A critical
overtemperature event occurs when the temperature value
stored in the temperature value register exceeds the value
stored in this register. The CT pin is activated if a critical
overtemperature event occurs. The temperature is stored in
twos complement format with the MSB being the temperature
sign bit.
